\ LOG-ROLLER.

SPECIFICATION forming part of Letters Patent No. 354,171, dated December 14, 1886.

Application filed July 13, 1886. Serial No. 207,861. (No mode-Ll To aZZ whom it may concern.-

Be it known that I, Lmnznus G. ORME, a citizen of the United States, residing at Paducah, county of McOracken, State of Kentucky, haveinvented a new and useful Machine to be Used in Connection with a Saw-Mill, of which the following is a specification.

The object of this invention is to scotch the logs on deck and transfer them to saw-carriage. I attain these objects by means of the mechanism illustrated on accompanying drawings.

Figure 1 is a sectional elevation of entire machine, with an end view of saw-carriage. Fig. 2 is a plan of the machine. Fig. 3 is a perspective view of the scotch. Fig. 4 is a perspective View of the arms.

Similar letters refer to si milar parts through out the different views.

The arms A A, bent in circular form, as shown, have teeth tformed on their top edges, are pivoted atB B, and are attached at their opposite extremity to a steam-cylinder or friction-bar.

A steam-cylinder, C, is shown in Fig. 1 connected to arms A A by connecting-rod E.

The scotch I) D oscillates on the shalt N. The ends of shaft N are carried in suitable bearings,one on each side. Thesides of scotch D D are connected by round bars F and O.

S S are stops in position, as shown, to prevent the scotch D Dtraveling too far in either direction.

The arms A A and the scotch D D are shown in Fig. l in dotted lines in the position they assume when log L is started toward the saw-carriage \V.

The action of this machine is as follows: The log L is shown in Fig. 1 resting upon the deck-rails. It is prevented; from moving toward saw-carriage \V by the scotch D D. Steam being admitted into cylinder 0, the arms A Aare forced up ward, striking the log L. As soon as the arms A A commence to move upward, their weight, which was resting upon the bar F, is removed, and the scotch D D, being thus released and pivoting on N, falls below the top of deck-rail into position indicated by dotted lines, Fig. l, leaving an unobstructed passage for the log L. The arms A A, first striking the log L, continue to rise until the end of stroke is reached, their top edges forming an inclined plane, upon which the log rolls onto the saw-carriage.

Having fullydescribed my invention, what I claim, and desire to secure by Letters Patent, 1s

In a log-rolling device, a scotch, D D, composed of two triangular frames connected together and pivoted to the frame of the mill, in combination with the curved arms A A, 11aving teeth formed on their upper edges to prevent the log from slipping, pivoted at one end to the mill-frame and engaging with the crossbars of the scotch, and mechanism for oscillatingsaid arms, with suitable stops connected to mill-frame to prevent the scotch from traveling too far in either direction, all substan tiall y as described and set forth.
